Gday fine Commodore people. Installing heads tomorrow on the ecotec VT and getting differing opinions on torque specs. The manual I downloaded says, in sequence: Stage 1. 34Nm. Stage 2. 90 degrees not exceeding 90Nm. Stage 3. A further 90 degrees. Problem is everywhere else I've read says stage 3 is 90Nm not an extra 90 degrees. What's the go?
Go with the manual Ecotec is in a variety of comodores it might differ model to model if you have a manual for a VT stick with that
Cheers mate, thanks for the reply. Gonna go with stopping at 90 Nm on the third pass as that's what everywhere else says, including the card the gaskets came with. Maybe the online manual I have got the wording all ar@e about.
